Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
CWE-522: Insufficiently Protected Credentials vulnerability exists that could cause unauthorized access to the project file in EcoStruxure Control Expert when a local user tampers with the memory of the engineering workstation.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

CWE-522 Insufficiently Protected Credentials vulnerability in EcoStruxure Control Expert allows a local user with the ability to tamper with engineering workstation memory to access project files without authorization. Credentials or encryption keys protecting project files are stored in memory in an insecure manner that can be extracted.

MitigationRestrict physical and privileged access to engineering workstations; implement proper memory protection mechanisms (e.g., encryption, secure storage) for credentials; review and harden credential handling throughout the application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed product
    Locate EcoStruxure Control Expert or EcoStruxure Process Expert in the system registry under HKEY_LOCAL_MACHINE\SOFTWARE\Schneider Electric or check Add/Remove Programs for the exact product name
    Affected if Either EcoStruxure Control Expert or EcoStruxure Process Expert is installed
  2. Determine installed version
    Check the product version in the Windows registry or by right-clicking the executable and selecting Properties > Details; common paths include C:\Program Files\Schneider Electric\EcoStruxure Control Expert\ or the application's about/help dialog
    Affected if Version cannot be determined or is lower than the affected release
  3. Compare against affected version ranges
    For Control Expert: compare your version to 16.0 (vulnerable if < 16.0). For Process Expert: compare your version to 2023 (vulnerable if < 2023). Use the full version string (e.g., 15.1, 15.2, 16.0) for accurate comparison
    Affected if Control Expert version is below 16.0 OR Process Expert version is below 2023
  4. Verify presence of project files
    Check for project files (.ecf, .xef, or proprietary project directories) typically stored in user-accessible folders under the application data directory or project workspaces
    Affected if Project files exist and the software version is within the affected range

Environment is affected if EcoStruxure Control Expert version is below 16.0 or EcoStruxure Process Expert version is below 2023, and project files containing credentials are present on the system.

Upgrade available Upgrade to 16.0 / 2023 or later
Fixed in 16.02023
Interim mitigation

Restrict physical and privileged access to engineering workstations; implement proper memory protection mechanisms (e.g., encryption, secure storage) for credentials; review and harden credential handling throughout the application.

Recommended fix Moderate confidence

Ecostruxure Control Expert version 16.0 or later; Ecostruxure Process Expert version 2023 or later

  1. Backup all project files and configurations from the current installation before proceeding
  2. Download the latest version of Ecostruxure Control Expert (version 16.0 or later) from download.schneider-electric.com
  3. Download the latest version of Ecostruxure Process Expert (2023 or later) if that product is also in use
  4. Install the new version on the engineering workstation following Schneider Electric's standard installation procedure
  5. Verify that project files can be opened and function correctly in the new version
  6. Review project file permissions and ensure credentials are now properly protected according to the updated security model
Caveat Review release notes for any changes to project file formats or features that may affect existing implementations
